I am not asking specifically for an opinion on that, I am needing to know which are available. I have one in my ride 2800 stall, but some suspicions on whether it is the correct one have risen due to its performance. Anyone know ?

 

Oh.. and I did not install it, but I had to order a second one because the guy who built my car had me get a 27 spline instead of a 25 (or vice versa). I think the 27 is in now.

 

the correct one would be one for a 700r4 ,the factory stall is around 1600, stall speed isn't a hard number and can change with weight and other factors

 

I was curious more about which models that B&M offered, and more so, should the input shaft be 25 or 27 spline (please pardon me if I got those numbers wrong).

 

An '87 would be 30 spline (early models were 27 spline).

You can see what they have available on their website, on summitracing.com or jegs.com.

What about your performance has raised this question? Many would say it's the fact that it's a B&M, but I won't go there.
